When a dude fucks a person pretty hard (male/female) that their stomach starts to hurt. Cum can make it worse.
Matt: "Just a bit of 'Lava Juice' from the stomach. It was a little violent, but I like to be rough sometimes."
Ilse: "It hurts, you bastard!"
Ilse: "It hurts, you bastard!"

Bowel movement that has warm and runny consistency similar to lava and composition that resembles the snakes of Medusa's hair.
Michael finished the Tai food and knew he would be battling the lava snakes for the next day or two.

When you cum carefully onto the small of a girls back and the jizz pools in the cleft. Optionally you can then move her around to play with the lava flow.
"Dude, I totally gave Nikki some back lava last night."
"What, like the pastry?"
"No, not baklava - BACK... LAVA.
"Oh... Gross."
"Yeah, and then I made her slap it so it erupted like a volcano! Then I made her clean it up... Stupid bitch!"

When you eat something unsettling with poo already in your rectum, the gas from the unsettling food then floats around your turds (like a lava lamp) creating intermittent pressure that you are afraid to release for fear of a shart!

The bowel movement after eating greasy food that is hot, steamy, chunky liquid; erupting like a volcano out of your anus.
Stan: "Hey Carl, you okay? You don't look so good..."
Carl: "Awh man no. I feel like shit, I just ate KFC and now I'm pouring Brown Lava every five minutes!"
Stan: "Ah bro, I know the feeling. I had Taco Bell last week and it did the same to me."
